i PNEUMATIC il To allwhom t may concern.'

Be it'lmown that I, O'r'ro zen of the United States, residing at New York, county of New York, State of N. Y., have invented new andl useful Improvements in Pneumatic rlires, of which the following is a specification.

I into a number of compartments.

The invention resides in the peculiar method of connecting the flexible annular partition with the member, so that when a pneumatic tire placed in one of the compartments is punctured, the tubing in the other compartment will expand and fill both compartments.

The invention is primarily designed to provide the shoe of a-pneumatic tire with a em'ble wire partition to divide the Vtire into equal compartments, the partition being adapted to swing over to the side ofl the casing when-one of the pneumatic tubes arranged in a compartment is collapsed.

The novel features of the invention are more fully described in the following speciication and claims and illustrated in the acelastic casin companying drawing in which:

Figure 1 represents a transverse vertical section of a tire embodying this invention.

Fig. 2 is a similar view showing the partition in a different Position.

Fig. 3 is a perspective view of a ie'xible partition.

Fig. 4 is a similar view of a modification. In this drawing the letter a designates an whlch as shown is in the form of a shoe a apted to be clenched to a rim' b of a wheel. Arranged -in the-casing adjacent to the tread is a band or loop o preferably formed of thin resilient material and adapted to centrifugally spring against the inner wall of the casing to prevent side shift and firmly hold it in place. Inother words, the band hugs the inner surface of the tire adjacent to the tread, but it could be formed of spring wire and perform the same function.

Application led December '20, 19116. Serial No. 137,952.

On the bandy is swingingly mounted a flexible partition consisting of a wire gauze member d projecting radially from the band to divide the casing into a pair of annular compartments. The gauze member and the band are preferably covered with a fabric or elastic material e which extends about the band and the gauze. As indicated in lFig. 3, one end of thegauze member terminates beyond the band, but is yieldingly connected to the band by the fabric.

As shown in Fig, 4, the gauze member is swingingly connected to the bandv by extending the member and providing it with a T shaped head f coacting with a strap g secured to the band. When one of a pair of pneumatic tubes It arranged in the com arti ments is punctured the 'Hexible partltion will swln over on to the collapsed tube along the innerI wall of the casing. The air in the other tube thenexpands and the tube will occupy the space formerly illed by the' said punctured tube. Each neumatic tube can also be independently in ated by valves j, or both can be inflatedsimultaneously.

The fabric can be secured to the wire gauze by rows of stitches c or it may be cemented thereto and the stitches omitted. artition is positioned on the collapsed tire, 1t vwill bend at the angle where it is joined to the band.l

The ends of the wire gauze and the band can be secured together in any well known way, for example, by welding, riveting or slot and stud fastening devices. The partition when in place in the casing practically forms a disk to circumferentially divide the casing into two equal annular chambers.
